A custom shader program.
|
|
|
|
Description
|
|
-----------
|
|
|
|
This class allows you to define a custom shader program that can be used by a :ref:`ShaderMaterial<class_ShaderMaterial>`. Shaders allow you to write your own custom behavior for rendering objects or updating particle information. For a detailed explanation and usage, please see the tutorials linked below.

|
|
- **MODE_SKY** = **3** --- Mode used for drawing skies. Only works with shaders attached to :ref:`Sky<class_Sky>` objects.

Method Descriptions

|
|
.. _class_Shader_method_get_default_texture_param:
|
|
|
|
- :ref:`Texture2D<class_Texture2D>` **get_default_texture_param** **(** :ref:`StringName<class_StringName>` param **)** const
|
|
|
|
Returns the texture that is set as default for the specified parameter.
|
|
|
|
**Note:** ``param`` must match the name of the uniform in the code exactly.
|
|
|
|
----
|
|
|
|
.. _class_Shader_method_get_mode:
|
|
|
|
- :ref:`Mode<enum_Shader_Mode>` **get_mode** **(** **)** const
|
|
|
|
Returns the shader mode for the shader, either :ref:`MODE_CANVAS_ITEM<class_Shader_constant_MODE_CANVAS_ITEM>`, :ref:`MODE_SPATIAL<class_Shader_constant_MODE_SPATIAL>` or :ref:`MODE_PARTICLES<class_Shader_constant_MODE_PARTICLES>`.

|
|
|
----
|
|
|
|
.. _class_Shader_method_has_param:
|
|
|
|
- :ref:`bool<class_bool>` **has_param** **(** :ref:`StringName<class_StringName>` name **)** const
|
|
|
|
Returns ``true`` if the shader has this param defined as a uniform in its code.
|
|
|
|
**Note:** ``param`` must match the name of the uniform in the code exactly.
|
|
|
|
----
|
|
|
|
.. _class_Shader_method_set_default_texture_param:
|
|
|
|
- void **set_default_texture_param** **(** :ref:`StringName<class_StringName>` param, :ref:`Texture2D<class_Texture2D>` texture **)**
|
|
|
|
Sets the default texture to be used with a texture uniform. The default is used if a texture is not set in the :ref:`ShaderMaterial<class_ShaderMaterial>`.
|
|
|
|
**Note:** ``param`` must match the name of the uniform in the code exactly.
